The Department of Justice announced the federal grand jury charges on Monday.

The five counts include stockingpiling ricin, a poisonous substance made out of castor beans, sending ricin-laced letters to Wicker, Obama, and Mississippi Judge Sadie Holand, and attempting to frame another person, Paul Kevin Curtis, with sending the letters.

According to the indictment, the three letters read:

No one wanted to listen to me before. There are still 'Missing Pieces' Maybe I have your attention nowEven if that means someone must die. This must stop. To see a wrong and not expose it, is to become a silent partner to its continuanceI am KC and I approve this message

The last line of the three letter was a deliberate attempt to use "phrases, verbiage and signature lines well known to be associated with Paul Kevin Curtis in order to make it appear that Paul Kevin Curtis was responsible," according to the Justice Department.

Three of the counts each have a maximum penalty of five years in prison and a fine of $250,000 and two of the counts hold a penalty of a maximum of 20 years in prison and $250,000.

The indictment is the latest development that began after authorities intercepted the letters to Obama and Wicker and subsequently put the Capitol on high alert. Curtis was initially the primary suspect in the case but law enforcement officials soon determined that he did not send the letters.

Dutschke, who has previously maintained his innocence in the case, is expected to appear in court in Oxford, Mississippi on Thursday.
